Sorry another stupid question .......whats the diff between different trangias? I mean between 1 person 2/3 persons etc is it just the cooking pans sizes or is it a diff size burner? Looking for something small like the idea of the trangia but also want to use a hobo type setup as my local woods are mostly peat and therefore not many places for an open fire. Have made a hobo (mark 1 not great) but was thinking about using a trangia burner in the hobo stove.......anyone got this type of setup? I also need new pots/billies as my old ones are not suitable so I'm starting from scratch. thanks D
